jarFilePath for HTableDescriptor.addCoprocessor() with 0.94.2 vs 0.94.4

[James Taylor]

In 0.94.2, if the coprocessor class was on the HBase classpath, then the 
jarFilePath argument to HTableDescriptor.addCoprocessor seemed to 
essentially be ignored - it didn't matter if the jar could be found or 
not. In 0.94.4 we're getting an error if this is the case. Is there a 
way to continue to get the old behavior? We've got HTables that were 
created under 0.94.2 in which scans will stop working if we upgrade to 
0.94.4 because our coprocessors will no longer be found.

Thanks,
